HEXONE Chemical compatibility with O-rings, rubbers, & plastics

Hexone, also known as methyl isobutyl ketone (MIBK), is an organic compound with the formula C6H12O. It is a colorless, flammable liquid with a characteristic ketone odor. Hexone is widely used as a solvent in the production of paints, coatings, varnishes, and adhesives. It is also employed in the extraction of precious metals, as a chemical intermediate, and in the manufacture of rubber chemicals. Hexone is valued for its excellent solvency properties and its ability to dissolve a wide range of resins and polymers. Handling hexone requires caution as it can cause skin, eye, and respiratory irritation. Prolonged exposure may lead to more severe health effects, including liver and kidney damage. Proper storage and handling procedures, including the use of personal protective equipment and good ventilation, are essential to prevent exposure. Hexone's role in various industrial applications underscores its importance as a versatile solvent.
